Subject [jira] Commented: (HARMONY-5554) [drlvm][jit][jet] Edge Profiler in JET
Date Thu, 28 Feb 2008 09:39:51 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12573196#action_12573196

Mikhail Fursov commented on HARMONY-5554:


IMO  SYNC mode for edge profile collector is useless. While it have a meaning for Entry-Backedge
profiler the typical "hotness criteria"  for Edge profile is a sum of all internal counters.
Checking this sum on every counter increment or even on every method-call is overkill.

I propose remove this mode support from the patch and support ASYNC mode only.
